See every featureHelp shoppers choose a jeans size using waist and inseam measurements. Upload a CSV size matrix, assign it to products, and add the size-finder block to your theme. Shoppers enter their measurements to receive a size recommendation. Requires body-measurement ranges for each size; garment dimensions alone are insufficient.
Size Buddy adds a Find my size button to your product pages. Shoppers answer a few quick questions, like height and weight or bust and hips, and get a size from your own size chart, with a clear explanation of how it fits. Start from a template for tops, bottoms, dresses, bikini tops or one pieces, adjust each size with sliders, and test any shopper before you save.
